A meta-analysis published in July 2025 demonstrates that higher consumption of ultra-processed foods is associated with a 22% greater risk of developing non-alcoholic fatty liver disease (NAFLD), with risk climbing 6% for every 10% increase in such foods. This observational data from 513,440 individuals arrives as Germany confirms a 2028 levy on sugar-sweetened beverages, a policy targeting one of the main vehicles for added sugar.

Clinical studies from the University of Zurich show that ingesting 80 grams of added sugar daily—less than a litre of soda—doubles fat production in the liver, an effect that persists for at least 12 hours. Fructose, whether from high-fructose corn syrup or table sugar, is metabolised almost exclusively in the liver, triggering pathways that mirror alcoholic liver disease, though without direct toxicity. Swedish cardiologists and a Russian neurologist separately warn that excessive sugar drives hypertension, atherosclerosis, and stroke risk, while the US-based Women’s Health Initiative linked high-glycemic foods to insomnia in older women, possibly through hormonal swings.

In Mexico, where NAFLD affects up to 50% of adults, researchers note the hepatic effect of fructose makes breakfast staples like industrial pastries and even pure fruit juice particularly detrimental. Swedish public-health figures are alarming: only 42% of Swedes know the national recommendation to eat at least 500g of fruit and vegetables daily, down 11 percentage points since 2022. The Heart-Lung Foundation estimates that if Swedes followed dietary guidelines, nearly 20,000 fewer cardiovascular events could occur by 2075. Conversely, protective foods are gaining attention: an NIH review of blueberries found promising evidence for cardiovascular and cognitive benefits, while oats and pumpkin are highlighted for their fibre and potassium in managing post-menopausal and age-related risks.

The German sugar tax, due in 2028, will be a key policy experiment, as it excludes naturally occurring sugars but targets added sugars in drinks. Researchers stress that whole-food alternatives—berries, whole grains, vegetables—not only avoid harm but actively counteract inflammation and oxidative stress. The coming year is likely to see further negotiations on sugar-reduction targets across the EU and renewed scrutiny of ultra-processed product labelling as the evidence linking diet to chronic disease accumulates.
